OK, maybe only 2 or 3 a year. Good old 0455. The elbows off the tree are looking pretty bad so I'll try to replace them first. My dealer doesn't stock them though! Grrrrrrr.
While tracing lines I noticed my purge valve is "square instead of "round". The dealer swears all '98's are round. Hmmmmmm. Anybody else with a 98 have a square?
